Abstract:
Vaccine misinformation circulated on social media has negatively impacted people's vaccine beliefs and behaviors. Communication strategies to address misinformation including fact-checking and warning labels have shown conflicting effects. This study examined how short-term exposure to vaccine misinformation impacted vaccination attitude through both cognitive and affective routes and tested whether and how two-sided refutational messages could negate the misinformation's impact. We conducted an online experiment involving a convenient sample of 609 U.S. adult participants with five message conditions: two misinformation messages (one using the conspiracy frame and one using the uncertainty frame), two corresponding two-sided refutational messages, and a control group. Results showed that both conspiracy and uncertainty framed misinformation messages decreased pro-vaccination attitude in comparison to the control. The two refutational messages increased pro-vaccination attitude in comparison to the corresponding misinformation messages. These effects were further mediated by the emotion of anger. Parental status and conspiracy beliefs did not moderate effects of the messages on vaccination attitude. Our findings indicate two-sided refutational messages can be a promising strategy to combat vaccine misinformation.
